- A bicyclist starting at rest produces a constant angular acceleration of 1.50 rad/s2 for wheels that are 33.0 cm in radius. HINT (a) What is the bicycle's linear acceleration (in m/s2)? (Enter the magnitude.) m/s? (b) What is the angular speed of the wheels (in rad/s) when the bicyclist reaches 11.4 m/s? rad/s (c) How many radians have the wheels turned through in that time? rad (d) How far (in m) has the bicycle traveled? Need Help? Watch It Read ItA diver makes 2.5 revolutions on the way from a 11- m-high platform to the water. Assuming zero initial vertical velocity, find the diver's average angular velocity during a dive. Number i Units(5) The angular speed of a disk decreases uniformly from 12.00 to 4.00 rad/s in 16.0 s. Compute the angular acceleration and the number of revolutions made in this time.
- 1) A solid sphere and a hollow cylinder are both rolling without slipping along a smooth horizontal surface at a translational speed of v = 6.35 m/s. They then encounter a hill. hmax a) Which object reaches a larger maximum height above the level ground? b) What is the maximum height the object from Part A reaches?An automobile engine slows down from 2500 rpm to 1200 rpm in 2.5 s. Calculate its average angular acceleration, assumed constanta) A diver leaps from a platform and immediately goes into a tuck position. If we assume that the diver has an initial angular velocity of 7.5 rad/sec, and has an angular acceleration of -0.22rad/sec2,how long will it take for the diver to complete 2 full revolutions?b) Assume that the diver is 6 m above the water with an initial vertical velocity of 1.74 m/s when she begins to rotate. Will she be able to complete 2 full revolutions before hitting the water? Why or why not?
- A cyclist is traveling at 32 km h-1. Calculate the angular velocity in RPM of the front wheel of the bicycle given that the diameter of the wheel is 700mm.12. A child and her father are playing on a spinning merry-go-round (a solid, horizontal disk). The disk is rotating at 0.400 rad/s. The disk as a mass of 200 kg and a radius of 5.00 m. The daughter (1) has a mass of 25.0 kg and is 3.00- m from the center of the disk. The father (2) has a mass of 60.0 kg and is 2.00-m from the center of the disk. a) The father moves to the outer edge of the disk, while the daughter moves inward until she is 1.00 m from the center. What is the new angular speed of the disk?Thank you. Shouldn't rotational kinetic energy be used, though, for part (b)?
